How To Fight Jet Lag
Your best bet is to adapt yourself to the routine of your destination’s time zone as soon as possible. Try these tips to avoid sleep problems when you travel:
- Several days before your trip, gradually adjust your sleeping habits to the time zone of your destination.
- As soon as you board your flight, reset your watch for the new time zone.
- While on board, try not to sleep too much.
- Drink plenty of fluids. Dehydration makes it harder for your body to adjust to the new rhythm.
- If you feel the need to nap right after you arrive, limit it to 2 hours.
- Try taking melatonin. This hormone can help you reset your bodyâs internal clock so you can fall asleep at the right time. Take a dose before bedtime at your destination every night until you adjust.
- Daylight can help reset your internal clock. Try getting some exercise outdoors, like a brisk walk, as soon as you get up in the morning.
- Donât drink too much caffeine or alcohol, and avoid tobacco.
- Try to keep yourself busy and engaged with other people.
- Practice good sleep habits while youâre away.
Work With Not Against Melatonins Sleep
Melatonin levels rise about two hours before bedtime, Buenaver says. Create optimal conditions for it to do its job by keeping the lights low before bed. Stop using your computer, smartphone or tabletthe blue and green light from these devices can neutralize melatonins effects. If you watch television, be sure youre at least six feet away from the screen. Turn off bright overhead lights too. Meanwhile you can help program your body to produce melatonin for sleep at the right time of day by getting exposure to daylight during the morning and afternoon. Take a walk outside or sit beside a sunny window.

How Does Melatonin Come At The Store
In the U.S., melatonin pills can be purchased without a prescription in the pharmacy, grocery, or health food store. Pill strengths range from 1 milligram to 10 mg, but you should always start with the lowest dose to judge its effects. Some experts suggest to start with 0.3 to 0.5 mg thirty minutes before bedtime, instead of the higher doses. Cut a 1-mg immediate release tablet in half to get a 0.5 mg dose if lower doses are not available dont do this with time release products. Also, don’t drink alcohol with the time-release preparation, as it can disrupt the time-release mechanism.
How Much Melatonin Do I Take At Night
For insomnia: 2 mg to 3 mg of melatonin before bedtime for up to 29 weeks has been used in most research. Higher doses of up to 12 mg daily have also been used for shorter durations . For insomnia occurring together with other conditions: 2-12 mg for up to 4 weeks has been used.

What Medication Can Interact With Melatonin
Its important to know how other medicines may interact with melatonin. As a general rule of thumb, consult your doctor before taking any new herbs or supplements.
Melatonin can reduce the effectiveness of some prescription drugs, triggering possibly serious complications.
For example, you shouldnt combine an anticoagulant or blood thinner medication with melatonin. Melatonin can increase the risk of bleeding.
Melatonin may also increase blood pressure in people who take medication to control their hypertension.
Other drugs that may interact with melatonin include:
- Anticonvulsants
- Selective serotonin reuptake inhibitors
Also dont take melatonin if youve been diagnosed with an autoimmune disease, like lupus.
Autoimmune diseases are the result of an overactive immune system, and inflammation is a classic symptom on these diseases. Melatonin can stimulate immune system activity, increasing inflammation and exacerbating an existing disease.
Does Food Contain Melatonin
A study published in Food and Nutrition Research notes that certain food products do contain various amounts of melatonin as measured by immunological and chromatographic laboratory techniques. How consumption of these various foods might affect endogenous production sleep or was not evaluated:
- Tomatoes
- Wine, beer
- Cows milk
Research finds that melatonin synthesis depends upon availability of the essential amino acid tryptophan, a needed component of the diet. If intake of tryptophan is severely restricted, synthesis of melatonin is significantly reduced in humans.
In the Nurses Health Study, no link was found between the consumption of various nutrients, such as folate, vitamin B6 and zinc and increased urinary excretion.
Diets rich in vegetables, fruits and grain products will contain considerable levels of dietary melatonin. The overall effect of dietary consumption on nighttime levels of melatonin is very limited. Melatonin production is primarily driven by the effects of light and darkness and by age, declining as we get older.

Is It Safe To Take Melatonin Every Night
Unfortunately, theres no straight answer here, which youre probably hoping for. There isnt any evidence proving conclusively that long-term use of melatonin is safe. Though the supplement is generally not associated with dependency, habituation, or hangover symptoms, Dr. Kohli says she doesnt suggest taking melatonin every night because of the lack of long-term clinical trials evaluating the safety of chronic use.
At the same time, there isnt any evidence proving nightly melatonin use isnt safe. Dr. Bollu points out that melatonin is a natural hormone that fluctuates in our bodies on a daily basis anyway, meaning it may be safer than taking a prescription drug.
However, thats a double-edged sword: Because melatonin supplements arent medications, they arent regulated by the U.S. Food and Drug Administration . Theres no guarantee about the quality of the product youre purchasing or the quantity of ingredients claimed on the label, unlike prescription drugs. A pharmacist or nutritionist may be able to help you find a product produced by a reputable manufacturer.
What Is The Usual Prognosis For A Melatonin Overdose
Melatonin is generally safe for most people, and many people wont experience major complications when taking too much. Even so, an overdose can cause unpleasant side effects.
Keep your dose to no more than 1 to 3 mg per night. See your doctor for any serious side effects or if sleep problems dont improve after a few weeks. You may need to consult a sleep specialist.
A sleep specialist can help diagnose a sleep disorder, as well as make other suggestions to help you get a better nights sleep.

How Much Melatonin Should You Take
The first thing you need to determine before landing on a melatonin dosage is why youre taking melatonin in the first place.
There are a number of different melatonin uses, and the reason why youre taking melatonin will certainly influence how much you should take. Your melatonin dosage will differ whether youre taking it for insomnia, jet lag, disrupted sleep-wake cycles, long-term sleeping difficulty or other reasons.
The perfect melatonin dose also differs between adults and children, as is explained below.
Who Should Buy Melatonin
Melatonin has a pretty targeted use, but a surprisingly large number of different categories of people find it useful. The sleep-promoting effects of melatonin make it a good first-line treatment for insomnia, and its uses extend to other situations where sleep may be compromised.
Older adults, who often have trouble sleeping, are also among the categories of people who may find melatonin useful indeed, melatonin has been used in clinical research on sleep disturbances in the elderly with good success.
Melatonin is a favorite among international travellers too, thanks to its ability to combat the productivity-sapping effects of jet lag.
With careful timing, a small to moderate dosage of melatonin can help reset your bodys biological clock and get you into your daily routine in a new time zone after travel.

Scientists Pinpoint Dosage Of Melatonin For Insomnia
MIT researchers reported in the October issue of the Journal of Clinical Endocrinology & Metabolism that doses of melatonin, a pineal hormone that is secreted by humans at night, can help older adult insomniacs obtain a good night’s sleep.
During the study, Richard Wurtman, the Cecil H. Green Distinguished Professor and program director of the Clinical Research Center, and other MIT researchers examined the ability of similar doses to restore nighttime melatonin levels and sleep efficiency in adults over age 50.
Two groups of subjects were involved in the study–one group who slept normally and another who experienced insomnia. Each subject received one-week doses of either a placebo or three different doses of melatonin in randomized order. Each different treatment was separated by a one-week “wash-out period.”
“According to our research, the physiological dose of melatonin of about 0.3 milligrams restores sleep in adults over the age of 50,” said Wurtman, lead investigator in the study. “The adults who would normally wake up during the second and third thirds of the night were able to sleep through the night with the 0.3 milligram dosage.”
The MIT scientists, who included Irina Zhdanova, former principal research scientist in the Department of Brain and Cognitive Sciences, also showed that low doses of melatonin affect sleep in young individuals and can help children with a debilitating neurological disorder called Angelman syndrome to sleep though the night.

Q: How Much Melatonin Should I Take To Help Me Sleep
A: Taking the sleep hormone melatonin is recommended to help induce sleep, but there is a good deal of confusion about how much to take. It is sold over the counter in a range of doses, from 1 mg to 10 mg and higher. The natural inclination is to take more melatonin if it is not effective in helping you sleep better, but this is not a good idea.

The hormone serotonin is produced during the day and this changes to melatonin when it gets dark outside. Peak levels of melatonin are produced before 3 a.m., when it sharply decreases before natural daylight returns.
Research has found that taking melatonin in low doses is the most effective way to promote sleep if you are experiencing restlessness or insomnia. Recommended doses of melatonin are from 0.5 mg up to 3 mg, which are adequate to promote sleep or treat jet lag.
When melatonin is used at higher doses, it tends to increase daytime sleepiness. Other side effects of too much melatonin can include reduced focus and concentration, feeling chilled and higher prolactin levels.
If you find yourself taking higher doses of melatonin, you can decrease the dose by cutting your tablet in half or in quarters. Research indicates there are no side effects if you reduce the dose of melatonin you are taking.

Why Melatonin Pills Are Bad
In 1993, MIT filed a patent for the best melatonin sleep dosage 1 mg or less. Dr. Richard J. Wurtman is credited as the inventor. The application was approved in 1995.
During the 20 years after that, dietary supplements couldnt legally sell capsules or tablets which were less than 1 mg. As such, they typically came to market with 3 and 5 mg pills, which is too much melatonin. Yet it was a way to circumvent the patent and avoid licensing it.
Given that using this substance for sleep was a novel idea, MIT could probably have claimed any dosage in their filing.
According to Dr. Wurtman, the whole reason they only pursued 1 mg or less was because:
They were wrong.
In the 1990s, the FDA had bigger issues to deal with, like nicotine addiction, and didnt bother to step in on this issue.
As a result, up to 10 mg melatonin supplements are the norm on store shelves these days.
Even though the patent has long expired, manufacturers continue to make these high dose melatonin tablets because the average consumer assumes that more is better. Since it sells better than a low dose version, they dont really have a financial incentive to sell the right amount.
Generic and lesser-known brands tend to use similar dosing amounts.

What Are Some Other Ways To Improve Sleep
You can improve sleep by keeping your bedroom dark, cool, and quiet, and switching off cell phones and other screens an hour before bedtime. Regular exercise, a healthy diet, and exposure to sunlight in the morning may also help regulate your natural melatonin levels. Tell your healthcare provider if you suspect you may have a sleep disorder, as this may require additional treatment.
Risks Of Taking Other Drugs With Melatonin
Taking melatonin in any amount can be dangerous if you are also taking certain other medications. Unfortunately, this includes medications that can also make it difficult to sleep. People who use blood pressure drugs, for example, may have a lower amount of naturally occurring melatonin. However, taking melatonin can cause blood pressure spikes, which could be incredibly dangerous.
On the other end of the spectrum, birth control pills can lead to elevated melatonin production. Taking a supplement could push your concentration into dangerous territory. Individuals using anticoagulants may see an increased risk of bleeding if they also use melatonin. Those on corticosteroids should also avoid the supplement. It also isnt wise to take melatonin in conjunction with caffeine or alcohol. Both of those substances impact circadian rhythms and natural melatonin production.

How To Choose A Melatonin Supplement
When choosing the best melatonin for sleep, it helps to understand how melatonin works and why some people may choose to take melatonin supplements.
Melatonin is a hormone produced by the pineal gland, located deep within the brain. It plays a central role in regulating circadian rhythms, which dictate behavior throughout the day and night. At night, the body increases production of melatonin in preparation for sleep. Melatonin levels stay high until the middle of the night and then start to drop down again in the morning.
Melatonin supplements were introduced as a way to help people who have trouble falling asleep. This external source of melatonin is intended to help bolster the bodys natural supply.
Shift workers, people with jet lag, and other people with irregular schedules or circadian rhythm sleep-wake disorders may find melatonin a useful way of adjusting their body clocks to meet the demands of their schedules. It may also help sleepers drift off after a stressful day. The American Academy of Sleep Medicine currently advises against using melatonin supplements for treating chronic insomnia.
The Food and Drug Administration considers melatonin a dietary supplement instead of a drug. Most melatonin supplements are available for purchase without a prescription, and they are not subjected to the same rigorous testing procedures as other medications. This means consumers should take extra care when purchasing melatonin supplements.
What Is A Safe Melatonin Dose
According to Michael Grandner, director of the Sleep and Health Research Program at the University of Arizona, melatonin is very safe if taken in normal doses, which is anything between 0.5 mg and 5 mg.
A 0.5 mg dose may be all thats needed for sleep-cycle regulation, and should be taken three to five hours before bed, he says. For people who want to take melatonin just before bed, a 5 mg dose is appropriate. Some people report headaches or stomach problems at higher doses, but those side-effects are uncommon, he says.
Still, there are other concerns. Melatonin has an incredible safety record, no doubt about it, says Dr. Mark Moyad, the Jenkins/Pomkempner director of preventive and alternative medicine at the University of Michigan. But its a hormone, and you dont want to mess around with hormones until you know what theyre doing.
People with existing medical problems should discuss melatonin with their doctor before using it. While some research has found that melatonin may help treat hyperglycemia in people with diabetes, for example, other studies have shown that, in diabetes patients who carry certain genetic traits, melatonin may interfere with glucose regulation. Its these sorts of contradictory findings that give experts pause when it comes to issuing melatonin a full-throated endorsement.

Can I Overdose On Melatonin
While severe side effects are unlikely, taking too much melatonin at once can disrupt your sleep-wake cycle and could result in next day grogginess. Because each personâs sleep cycle is different, as well as each personâs height, weight and sensitivity to hormones, there is no one-size-fits-all dose of melatonin that will work for everyone. Itâs best to start with a low dose of melatonin. If you give your body more than it needs, itâs possible to have the opposite effect and disrupt your sleep-wake rhythm, making it even more difficult to fall asleep.
